[Python-ideas] Preallocated tuples and dicts for function calls

Hi, what about the idea that the interpreter preallocates and preinitializes the tuples and dicts for function calls where possible when loading a module? Before calling a function then the interpreter would just need to update the items which are dynamic and then call the function. Some exa

Re: [Python-ideas] Add recordlcass to collections module

Hi, then intention of my first mail was to start a discussion about this topic about the pros and cons and possible alternatives. As long as it is not clear that recordclass or something like that is accepted to be implemented to the collections module I do not want to spend any effort on this

[Python-ideas] Add recordlcass to collections module

Hi, what about adding recordclass (https://bitbucket.org/intellimath/recordclass) to the collections module It is like namedtuple, but elements are writable and it is written in C and thus much faster. And for convenience it could be named as namedlist. Regards, Martin _

[Python-ideas] Do not block threads when pickle/unpickle

Hi, the old and slow python implementation of pickle didn't block background thread. But the newer C-implementation blocks other threads while dump/load is running. Wouldn't it be possible to allow other threads during this time? Especially could load/loads release the GIL, because Python

Of course I'm happy that Python is so much optimized. I'm only disappointed that I couldn't help to improve the speed with my idea ;-) On 2018-06-20 22:50, Guido van Rossum wrote: On Wed, Jun 20, 2018 at 1:16 PM Martin Bammer <mailto:mrb...@gmail.com>> wrote:

[Python-ideas] POPT (Python Ob ject Provider Threads)

Hello, because Python is a very dynamic language the memory management is heavily used. A lot of time is used for creating (reserve memory and fill object structure with data) and destroying objects. Because of this and because of the discussions about the GIL I was wondering if there isn't a sol
